7 Revolutionary Advantages of PPR Pipeline in Modern Water Supply & Drainage System

The global construction industry is undergoing a wave of green transformation, with the International Water Association showing that up to 25% of water supply systems are lost due to pipe corrosion. As a manufacturer of PPR piping for 15 years in the field of fluid transportation, we have been proven by 2000+ engineering cases – using ASTM certified PPR piping systems can reduce life cycle costs by 30%.

Part 1,Corrosion resistance PPR pipe vs metal /PVC pipe

1. The king of corrosion resistance: chemical inertia to crack the industry pain points

Traditional galvanized steel pipe in pH<6.5 water quality, rust in 18 months, and PPR pipe through the ISO 9080 standard of 10,000 hours of chloride test, acid/alkali/salt tolerance increased 47 times. A seawater desalination project in Dubai adopted our SDR11 specification PPR pipe, which has been running for 5 years without leakage.

2. Lightweight miracle: construction efficiency increased by 300%

The weight of DN20 copper pipe per meter is 1.2kg, and the PPR pipe of the same specification is only 0.15kg. A high-rise apartment project in Malaysia estimated that the PPR system reduced the installation time from 28 days to 9 days, saving $15,000+ in labor costs.

Part 2,Hot melt connection technology: the ultimate solution to end the potential water leakage

Molecular level welding: the leakage rate is reduced to less than 0.03%

The use of 260±5℃ intelligent temperature control welding machine,can achieve molecular chain recombination welding. According to the EN ISO 10508 pressure test, the bursting pressure at the welding place reaches 6MPa, far exceeding the national standard 2.5MPa.

Operation guide:

1. Cutting: Use a special pipe cutter to ensure that the perpendicality of the section is less than 1°

2. Heating: strictly control the heating time according to the pipe diameter (DN20 pipe needs 5 seconds)

3. Docking: Insert without rotation and maintain cooling time (see welding parameter table below)

Pipe diameter (mm)	Heating time (s)	Cooling time (min)
20	5	2
32	8	4

Part 3, The whole life cycle cost model: save in every 1 mm

50 year life promise: Maintenance costs drop 67%

The comparison of a hospital renovation project in Shanghai shows:

Galvanized steel pipe: 10 years maintenance cost ￥380,000

PPR system: 10 years maintenance only ￥125,000

We offer 10 years quality insurance.

Part 4, Health and environmental protection dual certification

seize the green building track

Food grade safety: through the NSF/GB/T 17219 double certification

(Authoritative endorsement: PPR pipe non-toxic certification)

PPR raw materials comply with FDA 21 CFR 177.1520 standard, lead content <0.01μg/L, especially suitable for maternal and child, hospitals/direct drinking water systems.

Advice for Project selection

– Residential project: Preferred S5 series cold water pipe

– Industrial piping system: The first choice is PN25 PPR Pipe high temperature (withstand 95℃ continuous hot water)
